There wouldn't be, it isn't an error ;-)

If you look at '/source3/locking/share_mode_lock.c' 'get_share_mode_lock'

The relevant part is this:

         status = get_static_share_mode_data(
             static_share_mode_record,
             id,
             servicepath,
             smb_fname,
             old_write_time);
         if (!NT_STATUS_IS_OK(status)) {
             DBG_WARNING("get_static_share_mode_data failed: %s\n",
                     nt_errstr(status));
             goto fail;
         }

It calls 'get_static_share_mode_data' and the relevant part of that is this:

     if (value.dptr == NULL) {
         d = fresh_share_mode_lock(
             lock_db, servicepath, smb_fname, old_write_time);
         if (d == NULL) {
             return NT_STATUS_NO_MEMORY;
         }

Which I hope you can see, is saying that it cannot find the share 
record, this isn't an actual error.

It has also been fixed in Samba git, see here:

https://git.samba.org/?p=samba.git;a=commitdiff;h=79e3b1c71f59591c54e87299984e50d2ffb00b6b

So, you can just ignore them ;-)
